What are Economic Sanctions and How They Work?

⚡ Quick Answer

Economic sanctions are legally enforceable restrictions — including asset freezes, trade bans, travel prohibitions, and financial penalties — imposed by governments or international organizations to pressure a target country, entity, or individual into changing behavior, without resorting to military force. In the United States, sanctions are administered by the Office of Foreign Assets Control (OFAC), a division of the U.S. Department of the Treasury, which oversees 30+ active programs as of 2026. Sanctions can be comprehensive (prohibiting virtually all transactions with a country — as with Cuba, Iran, North Korea, and Syria) or targeted/smart (freezing assets and blocking transactions with specific individuals or companies on the SDN List). The EU’s 20th Russia sanctions package (2026) targets over €360 million in exports and €570 million in imports. Violations carry civil penalties of up to $1.3 million per violation or twice the transaction value, plus criminal penalties of up to $1 million and 20 years in prison. Businesses exposed to sanctions risk should maintain an OFAC compliance checklist.

Sanctions have become a significant tool in modern politics, influencing economies, markets, and international relations. They are implemented to pressure governments, companies, or individuals, changing their actions or strategies. Economic sanctions hold a special place among such measures, as they have the most tangible impact on financial systems and trade processes. How does this tool work, and what makes it so effective? In this article, we will explore the essence of economic sanctions and the mechanisms of their operation.

What are Economic Sanctions?

Economic sanctions are special measures applied by governments or international organisations with the aim of influencing the economy of certain countries or individuals. They are designed to change the behaviour of target entities in response to their actions, which are considered undesirable or illegal. Economic sanctions encompass trade sanctions and financial relations, as well as various restrictions that affect international politics.

Sanctions can take various forms: from a full embargo that prohibits all economic relations with a certain country, to targeted sanctions that block transactions only with specific enterprises or individuals. Examples of economic sanctions include freezing assets, travel bans, and restrictions on the export of military goods.

Today, the focus is often on primary sanctions, which directly prohibit certain types of activities, encompassing both financial and trade restrictions.

So, what do economic sanctions mean for international relations? They are a crucial tool that allows countries to achieve political objectives without resorting to military force, while also hindering criminal practices such as money laundering and the financing of terrorism. It’s important to conduct regular OFAC screening and consult with Sanctions Lawyers to ensure compliance with these measures and to minimise the risks associated with economic sanctions.

When are Economic Sanctions Used?

Economic sanctions are applied to achieve political objectives, such as coercion, punishment, or deterrence of states and individuals who violate international norms. The primary reasons for imposing sanctions include:

  1. Counter-terrorism efforts: Sanctions are imposed to restrict the financing of terrorist groups and individuals.
  2. Non-proliferation of weapons: Used to prevent the sale or supply of weapons to countries that are developing them.
  3. Support for human rights: Sanctions can be imposed on states that violate human rights or hinder democratic processes.
  4. Response to aggression: They are used in response to military actions or aggressive acts, such as invasions.

Sanctions can take various forms, from export bans to asset freezing. They are considered a less costly means of influence compared to military actions. Economic sanctions are part of international law and often affect the foreign policy of countries.

Types of Economic Sanctions

An embargo is a comprehensive ban on trade with a specific country. An embargo can cover all types of goods, but in some instances, exceptions are allowed for humanitarian goods such as food and medical supplies.

Export restrictions prohibit certain goods, services, and technologies from being exported to target countries. This often includes a ban on the sale of weapons and high technologies that can be used for military purposes.

Freezing assets allows governments to block access to the financial resources of individuals or organisations that are subject to sanctions. This can include the seizure of bank accounts and a prohibition on managing assets within the jurisdiction of the sanctions.

Travel bans are imposed on government officials, businessmen, and their close relatives, prohibiting them from entering countries that enforce sanctions. This restricts their ability to participate in international events and enter into agreements.

These types of economic sanctions serve to achieve foreign policy objectives and reflect the importance of international law in controlling state behaviour.

What is the SDN List?

The SDN List (Specially Designated Nationals and Blocked Persons) is a register of individuals, companies, and organisations that are subject to US economic sanctions, maintained by OFAC (the Office of Foreign Assets Control of the US Department of the Treasury). Individuals on this list face various restrictions, such as asset freezes and prohibitions on conducting business with American companies.

The primary reasons for being added to the SDN List include supporting terrorism, money laundering, and other serious crimes. Being listed triggers severe consequences — consult our OFAC penalty calculator to understand financial exposure. The list is an important part of economic sanctions and is used to ensure compliance with international standards.

What are Extraterritorial Sanctions?

Secondary sanctions (also called extraterritorial sanctions) are economic and legal measures that a country imposes against individuals or companies located outside its territory, but which, in the opinion of that country, violate its laws or interests. These sanctions can include restrictions on financial transactions, trade restrictions, and asset freezes.

The primary goal of extraterritorial sanctions is to compel foreign states, companies, or individuals to adhere to certain standards of behaviour, even if they do not fall under the jurisdiction of the country imposing the sanctions. This may include combating terrorism, money laundering, or other forms of illegal activity.

For example, the USA employs extraterritorial sanctions to influence foreign companies that do business with countries under sanctions, such as Iran or North Korea. This means that even companies registered in other countries can be subject to sanctions if their activities contravene American laws.

To ensure compliance with extraterritorial sanctions, companies often seek assistance from Sanctions Lawyers for advice on adhering to regulations and avoiding potential legal consequences.

Do Sanctions Work?

The effectiveness of economic sanctions remains a subject of ongoing debate. They can be a powerful tool for exerting pressure, but their success depends on a range of key factors. Sanctions are more effective when they are supported by an international coalition, such as the UN or the EU, and are targeted at countries that rely on international trade. If the restrictions cover important sectors of the economy and last for a long time, their impact on the target country can be significant.

One example of the successful application of economic sanctions is the situation in South Africa during the 1980s. Sanctions imposed by the international community, including economic restrictions and a trade embargo, were aimed at pressuring the government to abandon its apartheid policy. These measures led to significant economic difficulties, which ultimately forced the government to enter into negotiations with the opposition and transition to democratic governance.

Other examples, such as sanctions against Iran, demonstrate that sanctions can achieve their objectives, especially when they are part of a broader strategy that includes diplomatic efforts. Thus, while sanctions are not always effective, they can be successful in achieving specific political goals when their application is well-planned and accompanied by other forms of influence.

Frequently Asked Questions

Q: What is the definition of economic sanctions?

Economic sanctions are coercive measures — including trade restrictions, asset freezes, travel bans, and financial prohibitions — imposed by governments or international organizations to pressure a target country, entity, or individual into changing behavior. They are used as a foreign policy tool that stops short of military action. In the U.S., the Office of Foreign Assets Control (OFAC) is the primary agency responsible for administering and enforcing economic sanctions programs, overseeing 30+ active programs as of 2026.

Q: What are the main types of economic sanctions?

The main types include: (1) comprehensive embargoes banning nearly all trade with a target country — e.g., U.S. embargoes on Cuba, Iran, North Korea, and Syria; (2) targeted or “smart” sanctions freezing assets of specific individuals or entities on the OFAC SDN List; (3) sectoral sanctions restricting specific industries such as Russia’s energy, defense, and financial sectors; and (4) secondary sanctions penalizing non-U.S. parties for dealings with primary sanctions targets.

Q: How do economic sanctions affect businesses in 2026?

Businesses must screen all customers, vendors, and counterparties against OFAC’s SDN List — updated daily. Violations, even inadvertent, can result in civil penalties up to $1.3 million per violation. In 2025, OFAC collected $266 million in penalties across 14 enforcement actions, while the EU’s proposed 20th Russia sanctions package targets over €360M in exports. Companies must maintain a robust OFAC compliance checklist and conduct systematic OFAC screening.

Q: What is the difference between primary and secondary sanctions?

Primary sanctions directly prohibit U.S. persons and entities from transacting with sanctioned parties or countries. Secondary sanctions go further: they target non-U.S. companies and individuals who engage in significant transactions with sanctioned parties — even without any U.S. nexus. This extraterritorial reach explains why banks and businesses worldwide comply with OFAC rules to preserve their access to the U.S. dollar financial system.

Q: Do economic sanctions work?

The effectiveness of economic sanctions is actively debated. Research suggests they work best when multilateral (backed by the UN, EU, and key trading partners), targeted at economically vulnerable sectors, and combined with diplomatic engagement. The South Africa apartheid-era sanctions and the Iran nuclear negotiations are cited as partial successes. However, effectiveness is limited by evasion networks and third-country workarounds. Understanding your OFAC penalties exposure is critical for any business operating internationally.
